Graphical abstract of the new research paper. The scientists collect samples from the rocks forming near hot springs and geysers. They dissolve small amounts of the rock in acid and organic carbon (created by living organisms) remains behind.

Photograph of new mobile telemetry trailer for the Cascades Volcano Observatory (CVO). The purpose of the trailer is to provide a communication link in the event that CVO needs to respond to a Cascade volcanic crisis at a volcano that is currently under-monitored (includes all Cascade volcanoes except Mount St. Helens).

Backscattered electron image of radiating fibers of kaolinite growing in volcanic rock altered by fluids connected to hot springs near Lassen Volcanic National Park. Associated with the kaolinite are rounded masses of silica and iron oxides (bright areas) that formed from pyrite. The composition and textures help us evaluate the origin of ore deposits and

Harrat Lunayyir basalt cinder cones and lava flows in Saudi Arabia seen from an aerial perspective. Deposits from the cinder cones cover nearby ridges and form fans at the base of the older non-volcanic ridge in the background. These well-preserved geomorphic forms indicate the relative youth of this northern part of the volcanic field.
